Specification of Letters Patent.

Patented March 19, 1907.

' To all whom it may concern.-

4 State of South Carolina, have-invented new and useful Improvements in Ventilators, of which the following is a specification.

The invention relates to an improvement in ventilating systems designed, primarily, for ap lication to railroad-cars or other powerdriven vehicles.

The main object of the present invention is the production of means whereby the vehicle may be efiectively lighted and supplied with filtered fresh air during its travel or while at rest, the invention further comprehending an improved means for drawing the vitiated air from the vehicle.

The invention Will be described in the following specification, reference being had particularly to the accompanying-drawings, in which Figure 1 is a vertical sectional view of the forward end of the car, illustrating the appli cation thereto of my invention. Fig. 2 1s an enlarged sectional view of the pump for use in my'system, the piston being shown in elevation. Fig. 3 is'an enlarged sectional view of one of the ventilators.

Referring to the drawings, 1 represents the car or other vehicle, on theaxle 2 of which is supported a drive-pulley 3, preferably split for convenient connection with' the axle. One end of the car is divided by a vertical partition 4 to provide a compartment 5, in

which the operating mechanlsm of the sys-' tem is arranged. Within this compartment is mounted a generator 6, driven from the pulley through the medium of a belt or.

split sproc et 7. A series of storage-cells 8 are arranged Within the com artment 5 and in electrical connection with the generator through conductors 9, whereby during the operation of said generator the current is stored in the cells. A light and fan circuit 10 leads from the storage-cells, being controlled by a switch 11. The circuit- 10 extends thrglughout the length of the car and to desire gize t e lights 12 and fans 13, positioned at any desirable or convenient points in the car.

' Each of the lights and fans of course are to be provided with their individual switches, whereby any one or more may be cut out without disturbing the others.

The ventilating system is operated through ee end of which opens to points thereof, being designed to enerable cylinder, in which is mounted a piston 15, "arranged to draw the vitiated air from the car and to draw in a supply of fresh air, as hereinafter described.

16 represents one ofa series of pipes arranged, preferably, longitudinally at any desired points in the car, each of said pipes being formed with a series of perforations 17, through which the vitiated air in the car finds its way into the pipe in the operation of the pump. The p'pe. or pipes 16 communicate, through the medium 0 a pipe 18, with the pump-cylinder near the rear end thereof,said pipe 18 being provided immediately adjacent sald cylinder with a cone-valve 19, opening by gravity toward the cylinder. Immediately and diametrically opposite the inlet, of

the medium of a pump 14, comprising a suitcylinder. The pipe 20 terminates in an open mouth in communication with the atmosphere beyond the bottom or side of the car. At the opposite end the ump-cylinder is 1prrovided with a fresh-air-mlet pipe 22, the the atmosphere beyond the end or side opening of the car and in which pipeis arran' ed a cone-valve 23, opening toward the cy inder. A feed- 'pe 24 communicates with the end ofthe inder, valve 25, opemng away from the cylinder. The feed-pipe communicates directly with a filtering-receptacle 26, preferably arranged near the roo ment 5 and in open communication wit the atmosphere through a funnel-pipe 27, opening through the end Wall of the car. The filtering-receptacle is in communication with the interiorof the car through a dischargepipe 28, extending longitudinally of the compartment 5 and opening through the partition 4 thereof into the body of the car through a funnel-mouth 29. By preference a suitable filtering medium 30', as sponge or the like, is arranged in the receptacle 26, and in order to maintain this material in the desired condition I provide a tank 31, which is secured to the car above the filtering-receptacle and is in open communication therewith through a pipe 22. signed to contain water or other desirable fluid by which the filtering medium within the receptacle 26 is maintained in desired moistened or antiseptic condition.

being provided with an outlet coneor upper end of the com art- The tank 31 is de- IIO ' car and is designed to operate asei ies of fan", shafts 36, but one of which'is shown, handing;

- While the car is motion the pump 14;

and generator 6 aredri'ven directly from thecar-axl'e, the lightingand' fan system forming the sole demand upon the storage battery. It may be found desirable, however, to 'mechanically. operate the fan system, and to this end Iarrangea power-shaft .33, driven by cog-gearing from a helt-wheelg34, open-f ated by a'belt 35 upon the generator-shaft,

The power-shaft extends vertically of: the

, to the various located fans throu hout the car, it being understood that this eature of theinvention contemplates the arrangement of the power-shaft and such counter-shafts as may be necessary in order to operate each of: the fans. To provide for disconnection of the power and fan shafts inthe event of the electrical operation ofthe fans, I arrange the operating-gear, on the power-shaft at the end cles 39, suitably fixed in the sides of the car andin communication. with the atmosphere through a. short section of pipe 40, having a 'cationwith a su ply-tan flaring mouth, the connection? between said pipe and receptacle being such as to ermit ndependent movement ofthe pipe, w ereb'y desiredfdireotionin accordance with, the travel ofthe car.

ceptacle is adapted to contain a suitable filitering medium 42, through which the airpassing through the pipes 40 is compelled to pass prior to its admission to-the car; If desired, the receptacle. 39 ma be in communir similar to .31, whereb to maintaln the filtering medium 42 inthe esired condition.

' Durin previous y described are operated through; the medium ,of the belt 7, driven by the axle of acar, while during the state of rest of the car the parts are operated by the power stored in the-storage battery 8, it being un-' derstood that in this event even the generator '6 becomes a motor to operate the pump an ,other parts. In this event,;ofcourse, the belt 7 is tobe disconnected from operative connection with the axle-pulley 3 b. any

suitable 'means, such as an ordinary c utoh,

whereby the parts may be operated: under the'i'nfluence of the storage battery without operating the belt.

It is to be understood that inordina circumstances I contemplate theuse-of, aesh- 1 subwa s, or-the like. to arrange'the mouth thereof to open inithe'; I

A filtering-cham er apparatus at each and other, hilt that fparatus, desired, andto 'providelfor" the 10-.
